Dab tsi yog Cov Khoom Ntawm Aluminium?

Nws yog ib lub teeb hlau heev, tsuas yog ib feem peb ntawm cov hlau loj. Aluminium yog tsis tshua muaj malleable thiab muaj zog: nws tuaj yeem kos rau hauv cov hlau los yog nias rau hauv cov ntawv nyias nyias. Aluminium kuj muaj cov tshuaj lom neeg txawv txawv. Ntawm ib sab, nws zoo li tsis ntshai ntawm oxidation, raws li peb tuaj yeem pom los ntawm POTS, POTS thiab lwm yam khoom siv txhuas; Tab sis ntawm qhov tod tes, aluminium muaj qhov sib txuam zoo heev rau oxygen. Qhov no zoo li yog ib qho kev tsis sib haum xeeb ntawm qhov xwm txheej, tus kws tshawb fawb Lavxias zoo tshaj Dmitri Mendeleev tau taw qhia ntxov. Qhov teeb meem yog tias, sai li sai tau thaum lub silvery aluminium refined, nws coats huab cua nrog ib tug nyias zaj duab xis ntawm dull alumina, uas tiv thaiv oxidation ntxiv. Tsis yog txhua tus hlau muaj peev xwm tiv thaiv tus kheej no. Txhua leej txhua tus paub, piv txwv li, tias oxide ntawm hlau, xeb, tsis muaj dab tsi los tiv thaiv nws los ntawm oxidation ntxiv: nws yog nkig heev uas nws yooj yim nkag tau los ntawm huab cua thiab dej. Cov oxide zaj duab xis, ntawm qhov tod tes, yog li ntom thiab elastic tias nws yog txheej txheej tiv thaiv zoo rau txhuas.

Thaum txhuas yog rhuab, nws ua nruj ua tsiv nrog oxygen thiab ua alumina, muab tawm ntau heev ntawm tshav kub tib lub sij hawm. Cov cuab yeej ntawm kev tso cua sov no thaum aluminium hlawv tuaj yeem siv tau los rho tawm cov hlau los ntawm oxide ntawm lwm cov hlau los ntawm kev sib xyaw cov hmoov txhuas hlau nrog cov hlau oxide. Cov txheej txheem no yog hu ua thermite, nyob rau hauv uas cov hlau yog txo los ntawm stripping oxygen los ntawm oxides ntawm lwm yam hlau.
